The basic configuration of CMTS :
1) Check if every card is up and recognized from CMTS.
#show inventory
2) Place the ip on GigabitEthernet):
interface GigabitEthernet1/0/0
ip address 172.22.0.22 255.255.255.0
negotiation auto
no shutdown <<<(Make sure that the interface is UP)
!
3) Set ip Default Gateway
ip route 0.0.0.0 0.0.0.0 172.22.0.1
!
4) Check the connection with router
5) For Telnet access we need to create a username and password:
Also we must configure VTY for allowing us from Telnet:
6) Configure bundle interface :
Configuration of Router (in our cases Mikrotik):
1)Set ip address in WAN interface and connect to the Internet:
2) Create a route to the internet:
3) We can NAT everything >>IP >>Firewall>> NAT:
4)Now, create a Bridge Interface >>BRIDGE
>>>IP >> Adresses >> "+":
6) Put the Ports that you have connected CMTS and Server in the Bridge interface >>BRIDGE >>Ports >>:
7) We need to route CM-IP and CPE-IP to the CMTS IP Address >>IP >>Routes >> "+" :
8) Check if we have ping with CMTS and SERVER
Configuration of SERVER(LINUX):
1)Set an IP address on Server >> Setup >> network configuration>> Device configuration >> eth0 >>
2)TEST you connection :
3)Configure the DHCP header >> nano /etc/dhcpd.conf :

2) ADD routes on >> nano/etc/rc.local
3)Make sure that these routes are on >> route -n :
